Intel D87C51FC - MCS-51 microcontroller (1980) : weekend die-shot
8051 (MCS-51) is a grandfather of today's embedded electronics, and probably can still natively run 20% of embedded code in use today. 87C51FC is a version where internal PROM is replaced with EPROM. It has 32KiB of UV-erasable EPROM and 256 bytes of SRAM. This is the first chip to survive Zeptobars lab visit as I have more plans for it. Die size 6143x4380 µm. EPROM cell size 12.76µm², SRAM cell size 470.5µm².
